Correlation map in GrADS

I am new in GrADS and I am trying to plot a field of correlation between two variables (Precipitation and Temperature) but I could not make it. I have tried with some libraries but it neither works.

Can you help me with that?

See the following links:

[1] Spatial Correlation http://cola.gmu.edu/grads/gadoc/gradfuncscorr.html

[2] Temporal correlation http://cola.gmu.edu/grads/gadoc/gradfunctcorr.html

You can also use cdo:

cdo fldcor  infile1 infile2 outfile
cdo timcor  infile1 infile2 outfile

See this link for details:

Did you have tried with the method given here. You can use fcorr.gs script. In another way you can use CDO.
